EMVANV Paint Thickness Gauge, Digital Meter Probe Paint Thickness Gauge Zero Calibration Digital Display Car Coating LCD(White)

Works great. I knew the used Mercedes from Carmax was partially painted. This gave the same consistant readings repeatedly. RePainted area read from 0.24 to 0.30mm , whereas non-repaintet was approx. 0.16mm. Traded the car in on another used Carmax car, but not before going over it with this paint depth reader. Reads between 0.14 and 0.16 mm on new car throughout. Don,t spend any more money than you have to.

Good quality

While shopping for a used car this device came in very handy to help uncover undisclosed damage by unscrupulous sellers and dealers. From what I can tell it's accurate within +3 millimeters. Take that into consideration when using.

This thing works perfectly to sync it or calibrated it's very easy just press the power button and the top right hand side one. The directions are terrible all you do is you first do that metal piece without anything and then add the films to it and it'll calibrate itself

Had to return. I purchased a used car that sometime in its life had been repainted. I wanted to measure the clear coat to know if it would be safe to do some correction work on. This gauge will not accurately measure clear coat on a vehicle that has been repainted. Nothing wrong with the gauge as far as I know it just wasn't what I needed.
